Tertiary aromatic amines derived from aminoglutethimide or para-aminophenylacetic acid act as accelerators for the peroxide catalyzed polymerization of acrylic resins, especially methacrylates, acrylates and unsaturated polyesters. The amines are characterized by good hardening, strength, color and toxicity characteristics, and are thereby particularly suited for use in the filling and restoration of human teeth and the cementing of bone.

Tertiary aromatic amine accelerators in acrylic resin

Cementitious dental compositions suitable for use as luting agents, sedative and insulating bases, temporary and long term restoratives, endodontic sealants, pulp capping materials, tissue packs, impression pastes and adhesives for dental composites and hard tissues comprising a solid phase which includes a metal oxide or hydroxide of tin or a Group II metal and a liquid phase which includes a chelating compound, the chelating compound being an ester of a vanillic acid moiety in which the ester is the product of a reaction of one of an alcohol, a polyhydric alcohol or a polyalkylene glycol and at least one of either vanillic acid or its isomers or homoloynes. The compositions may additionally contain a second chelating compound, Al.sub.2 O.sub.3, an hydrogenated rosin, polymeric materials and polymerizable monomeric materials.

Cementitious dental compositions which do not inhibit polymerization

Tertiary aromatic amines derived from para-aminophenethanol act as accelerators for the peroxide catalyzed polymerization of vinyl monomers, especially methacrylates and acrylates, and for the curing of unsaturated polyesters. The amines are characterized by generally high reactivity and low toxicity, and by their yielding polymers of high strength and low color, and are thereby particularly suited for use in polymerizable or curable formulations employed in the filling and restoration of human teeth, in the preparation of cold-curing denture base materials for fabricating or repairing dentures and in the cementing of bone.
